1.1 Packaged Gas Supply 1.1.2 CYLINDER PALLETS
Air Liquide Singapore supplies a comprehensive range of industrial, specialty and medical gases in pallets of various capacities, which are safely and promptly delivered to your doorstep for your application.
Cylinder pallets are used extensively in the shipyard and construction sectors and are the preferred choice for our customers who are seeking the following attributes:
1. Convenience Since the pallets normally come in 4 to 16 cylinder bundles, customers do not need to change cylinders as frequently as
compared to individual cylinders.
2. Safety Cylinders that are bundled in a pallet are more robust. Their stability and mobility make them well-suited to the shipyard and
construction industries.
Our 300 bar pallet is an innovative supply mode that combines a higher capacity design with an easy-to-use interface to simplify operations. The benefits are:
1. Simplicity Clear user interface with an integrated content gauge informs users of residual content at all times Simple on-off lever for opening and closing the flow of gas
2. Performance More capacity: 45% more gas than standard 200 bar bundles leads to reduced handling and storage requirements Integrated pressure reduction feature allows for hook up to standard installations without the need to upgrade to higher pressure equipment Cost savings from reduction in rental and logistic costs
3. Safety and Reliability Effectively reduces handling frequency thus reducing the frequency of potential accidents On/off lever allows for identification of opened valves preventing gas leakage and related safety issues Integrated content identifies how much gas is left in the pallet reducing the risk of running out of gas during usage Designed with Air Liquide safety know-how and expertise

Dry Ice, the solid form of Carbon Dioxide (CO₂) at temperature of -78.5 ºC, is tasteless and odorless. It is used to address critical temperature control requirements during food production and packaging, and provide refrigeration during transportation and distribution.
As the shelf life of dry ice mainly depends on the storage box integrity, we employ the following containers to minimize the sublimation loss.
There are two types of containers available:
The raw material for manufacturing of dry ice, liquid CO₂ is produced by Air Liquide Singapore owned CO₂ plants.
Dry ice comes in 3 forms: blocks, slabs and pellets. Each form is designed for specific needs.

Our LGCs are designed to withstand normal handling and vibration in transit. Nevertheless, there are various precautions that need to be adhered to for the safe handling of our LGCs.
Usage and Storage Store and use in a well ventilated area. Close all valves when LGC is not in use. Apply no oil or grease on any fittings on the vessel or its connecting pipework or hoses.
Transport Keep the vessel upright for use and transportation. Do not manoeuvre the trolley on uneven surfaces as it may topple and injure the users Never remove the vessel from its trolley frame. Avoid rough handling, dropping or striking. As there is a vacuum between the outer and inner vessels, a blow on the outer
vessel can render the LGC unserviceable.
Handling Cryogenic Liquids Care must be taken to avoid contact with liquid or any uninsulated parts of the vessel as it can cause severe cold burns. Protective clothing (leather gloves, face-shields, aprons etc) should be worn.
Maintenance Do not attempt to carry out maintenance to the LGC on your own. Contact Air Liquide Singapore in case of any suspected defect or malfunction. Do not change identification lettering or labelling on the LGC, make modifications or alterations to the LGC or fittings.

Gas or liquid can automatically be dispensed at a pre-set pressure by means of an inbuilt vaporiser and pressure regulator.
For Gas Withdrawal 1. Connect adaptor and regulator on to the Gas Use Valve (8) outlet. 2. Open Pressure Building Valve (3) and also the Gas Use Valve (8). The pressure will reach the preset operating pressure ..
and maintain it. 3. Do not attempt to adjust the Pressure Building Regulator (2) as it has been factory-set to achieve correct operation. 4. When gas is no longer required, first shut the Pressure Building Valve (3) and then shut the Gas Use Valve (8). 5. If the LGC is kept unused over an extended period or if the Pressure Building Valve (3) is left open after use, there is a possibility that the Pressure Relief Valve (7) will release the excessive pressure. This is a normal phenomenon. The pressure can also be reduced by slightly opening the Vent Valve (4) in a well ventilated area. 6. Formation of ice on the outer shell is expected in cases where the draw-off rate of gas is excessive under prolonged usage.
For Liquid Withdrawal 1. Connect one end of the stainless steel liquid transfer hose to the Liquid Use Valve (1) outlet on the LGC and the other end
of the hose to the user’s equipment. 2. Liquid withdrawal from a liquid cylinder is normally performed at low pressures to minimise flash vaporization losses. Therefore, the Pressure Building Valve (3) is normally kept closed during liquid transfer. If pressure exceeds the user’s requirement, the excessive pressure can be released through the Vent Valve (4). 3. Higher service pressure can be obtained by opening the Pressure Building Valve (3) up to the desired pressure and then
shutting it. 4. Keep the transfer hose as short as possible to minimise gas loss. 5. Lines between the two valves must be equipped with a safety release valve. 6. When filling an open neck dewar, fit a phase separator on the end of the transfer hose to minimise flash-off and spillage.
